To' all whom t may concern: Y

Be it known that 1, MARY R. ARTHUR, a citizen of the United States, residing at Joplin, in the county of Jasper and State of lliissournhave been appointed executrix of the last will and testament of Janus B. ARTHUR, late a citizen of the United States, deceased, who invented certain new and useful improvements in Ore Goncentrators, of which the following is a specification.

This invention relates to ore concentrators and the present application is a division of the copending application Serial No. 360,434 Feb. 21, 1920. The principal object of the present invention is to provide` means for feeding the crushed ore and distributing the same in a more uniform manner than heretofore over the rotary table upon which the concentrates are collected, to the end that more of the concentrates may be recovered than heretofore. v

1n order that the invention may be fully understood, reference will now be had to the accompanying drawings, in which:

Fig. 1 is a front elevation of the concentrator equipped with the feeding and distributing mechanism.

Fig. 2 is an enlarged broken vertical section on line 11Il of Fig. 1, with some of the parts removed.

Fig. 8 is an enlarged, fragmentary cross section on line 111-111 of Fig. 2.

4 is an enlarged fragmentary cross section. on line lll-1V of Fig. 2.

Referring now in detail to the various parte, 2 designates a suitable frame,y in the center of which a vertically-disposed shaft 4 is mounted. Said shaft4 is journaled at its upper portion in a bearing 6 and at its lower end in a step bearing 8.

10 designates a 'rotaryy table having a flat bottom portion` upon which the crushed ore is fed, and a centrally-disposed hub 12 keyed or otherwise fixed to the shaft 4 in orderto rotate therewith.

rEhe table 10 is provided with a lixedlymounted centrally-disposed drum 50, which is surmounted by a conical distributor- 52 fixed to the lower end of a tubular shaft 54, journaled on the sha-ft 4 and resting upon a collar 56 fixed to said shaft 4. The margin of the distributor 52 is surrounded by an annular guard 58 supported by arms 60 secured to the periphery of the drum 50. As

Vbearing 126 surrounding the shown more clearly on Fig. 2, the guard 58 is spaced `from the circular margin of the distributer. 52 to leavean annular Vspa-ce 61 for the passage 0f the crushedore from said distributer 52 tothe table 10.

62 designates a rotary hopper disposed above the distributer 52 and supported by hangers 64, adjustably connected at their upper ends to a sleeve 66 havin'g a grooveand-feather,connection 68 with a tubular shaft T0, journaled. upon the tubular shaft 54 and `resting upon a flange 72 fixed to said tubular shaft 54. y Y

rThe hopper 62 may be raised and lowered to vary the space between its discharge end and the distributor 52, by means of a lever 74 operably connected at its bifur'cated end to a band 7 6, loosely mounted in a peripheral groove in the sleeve 68 to permit said sleeve to rotate without rotating the band 7 6 and said lever 74. The lever 7 4 is mounted upon a fulorum 78, carried by an arm 79 having aY notched segment 80 whereby the leverI 74 is held in any of its adjusted positions.

r1`he shaft 4, carrying the table 10 is .provided at its upper end with a bevel gear 82 meshing with a bevel gear' 84, fixed upon a drive shaft 86 journaled in bearings 88 on top of the frame 2 and provided withv fixed and loose pulleys 90 and 92, respecf tively.

The tubular shaft 54 is provided at its upper end with a bevel gear 94 intermeshing with a bevel Gear 96 fixed upon a counter shaft 98 provided with another bevel gear 100, intermeshing with a bevel gear 102 fixed upon a vertical shaft 104'provided at its upper end with a. bevel gear 106 driven by a bevel gear 108 loosely mounted upon the drive shaft 86.

The tubular shaft is provided at its upper end with a bevel gear 110 intermeshing with a bevel gear 112 fixed upon a countershaft 114 provided with another bevel gear 116 driven by a bevel gear 118 fixed upon the lower end of the vertical shaft 104, which is journaled in a bracket- 120 depending from the frame 2. The Vcounter shafts 98 and 114 are journaled in hangers 122 and 124 depending from the upper portion of the frame 2. The hanger 122 carries the notched segment 80 and is provided with a tubular shaft Thevbeyel gear 108 is loosely mounted upon tthe drive; shaftL 86 butiay be aiise'd to rotate therewith at Will through the intermedia@ Ote, Glutei-1; 13@E ,haring a groove.- and-feather connection T32 Vwith said` drive shaft 86 and controlled by Aa hand lever IBZL In the practical operation of the kmachine, the clutch 130 is shifted into engagement with Vtheflbevell gearlOS' to drive the 'dis' tributor 52 and the hopper `62in reverse upon vthe distributor'52 the guard 58A prevents said ore frintbeiiigeast'off byl 'centrifug'al force and directs itWlwnwfardly around the druin' 50 froni `Whereit' spreads e'yenly offer the table VIO. If it' is desired to feed the Vore rapidly to the distributor 52, the .lnoi'jper G2 vis raised 4'by proper nianipulationofthe lever 4to' increase' the size of the" opening' between the -loiver endl of said hpperi624 andthe 'top vof the distributor 52,

and slower feed :isf desired the hopper 62 is loweredto reduce the size ofthe opening. As Ythe"crushed fore and the' accompanying Water flow outwardly upon the table l() towardstherini 16, the Waterbeing lighter thanthe ore is forced to the top and'escapes through spouts 26 as fully set forth in the parent application above-mentioned. After the ore attains the desired depth upon the tble'l() the belt' is shifted` from the tight piley 9,0 to the loose pulley 92 to'bring the moving' parts to a stop.

Having thus described` my invention, what I clkiiinand desireto secure by Letters Patent,is=:"" l

In an apparatus of the characterdescribed a rotary table'having a flat bottoni portion 'i'iinfiied thereto, a centrally disposed drinn fixed to said table, a conical distributor spaced above and"overlapping vsaid druni,a guard spaced' from and' encircling said dis-A ti'ibutor,'ineans vsupporting said guard 'and secuifed'to the drinn, and ineens for eonti nuously driving the `ta'bleandA the distributor' in opposite directions.

In testnn'ony whereof, I n'iy signature iny the vpresence of ,two Witnesses.
